Pascal Secures $8.5 Million to Modernize Refrigeration Technology

Co-founders Adam Slavney and Jinyoung Seo stumbled upon the breakthrough while conducting high-pressure material tests. What began as a confusing data discrepancy evolved into a unique refrigeration method that uses carbon dioxide and a proprietary sponge-like material. Unlike conventional systems that rely on gaseous refrigerants like Freon or R-134a, which pose severe ozone and climate risks, Pascal’s solid-state approach traps the cooling mechanism within a secure cartridge.

The system functions by cycling carbon dioxide through porous material, where molecular collisions transfer thermal energy. By running two cartridges in tandem—alternating between heat absorption and exhaustion—the device maintains cooling cycles without requiring the extreme pressures typical of other experimental solid-state solutions. Slavney reports the material has already withstood 300,000 cycles, proving its robustness for long-term use.

With fresh capital co-led by Sazze Partners and LB Investment, the Massachusetts-based team is accelerating its production timeline. A pilot program with a multinational beverage company is already underway, and the company expects to deliver its first prototype early next year. If the technology performs as expected, Pascal aims to move into broader commercial manufacturing by 2028, leveraging conventional system components to keep costs low and adoption widespread.
